Q: Could you offer the free samples ?
A: Yeah, but it depends products, Pls contact us [email protected] or whatsapp 0086 15168536055
Q: What ' s your business scope ?
A: Our business scope is service of exporter automation parts with full container, and sell air cylinder , air source treatment , solenoid valve , air valve, motorize valve , Brass valve, hydraulic valve, hydraulic cylinder, air and oil fitting, pressure gauge etc .
Q: What types of products you can make ?
A: We can make many kinds of stainless steel, brass ,aluminum materials processing .like high pressure Valve / solenoid valve / electric valve / water valve/pneumatic valve/air cylinder/hydraulic valve/hydraulic accumulator products and so on .
Q: Can the product be made with our logo and brand ?
A: Yes , of course , we can make . we are OEM supplier for years
and professional to make . But you need give us the authorization
if it is possible .
Q:Can you provide original famous pneumatic and
hydraulic,instruments brand goods ?
A: Yes,We can supply like
Festo,Smc,Ckd,Burket,Hydac,Rexroth,SMS,RSMT,Marsh ,Endress+Hauser
etc.
Q: Is there a warranty available?
A: Yes, normally products is one year quality guarantee.
Q: Is the connector in British or Metric system? What is the
difference between PT, NPT, and G threads?
A: The G thread is cylindrical and does not seal itself, requiring
additional gaskets to prevent leakage. PT and NPT are conical, and
the internal and external threads become tighter and tighter when
tightened. Sealing is achieved through the deformation of the
threads, and sealant or tape is usually used in conjunction to
enhance the sealing effect
G-thread is a cylindrical straight pipe used for non sealed
connections; PT thread is a conical tube that relies on the
deformation and sealing of the thread itself; NPT is also a conical
tube with a tooth profile angle of 60 degrees, mainly used in North
America
Q: How to convert pressure units: MPa, bar, psi, kg/cm ²?
A: 1MPa=10bar≈145psi≈10kg
Q:What usually causes the burnout of solenoid valve coils?
A:Incorrect voltage and hz, frequent switching, pilot head entering
liquid,valve core and spring problem,environment hot,heavy vibration etc.
Q: What should be noted for pneumatic components in high temperature
or extremely cold environments?
| Focus Point | High Temperature Environment Countermeasures | Extreme Cold Environment Countermeasures |
| Seals | Fluororubber, PTFE | Low-temperature nitrile, silicone rubber, polyurethane |
| Lubrication | High-temperature synthetic grease (low volatility) | Low-temperature grease (low pour point, low viscosity) |
| Air Supply Treatment | Strengthen cooling, efficient water removal | Ultra-low dew point drying (refrigeration + adsorption type), heat
tracing |
| Metal Components | Reserve expansion clearance | Select materials with low-temperature toughness, prevent leakage
due to cold shrinkage |
| Control Components | High heat-resistant grade coils, heat dissipation, low power
consumption | Install insulation boxes, local heating, prevent cold condensation |
| Installation | Keep away from heat sources, add heat insulation plates | Avoid exposure to wind and snow, wrap with thermal insulation
materials |
